Scalp myiasis associated with soft tissue sarcoma lesion: a case report and review of relevant literature. Sarcophagidae is one of the main fly families that is attracted to open wounds, ulcers, lesions, and other injuries for depositing their larvae. The presence of larvae of flies in human tissues makes myiasis. Myiasis on the scalp could be more frightening in comparison with myiasis on the other parts of the body. It is a rare myiasis case that shows the ability of myiasis agents to attack various parts of the body. On the other hand, reporting of myiasis cases by Sarcophagidae larvae is not common due to difficulties in their identification. This study aimed to emphasize the importance of Sarcohagidae larvae in producing myiasis by describing the first case of soft tissue sarcoma
The periscope sign as a new dermatoscopy finding to facilitate the diagnosis of furuncular myiasis. In this text, we introduce the ‘periscope sign’ as a novel dermatoscopic finding in furuncular myiasis. This clinical sign may aid in diagnosing this rare condition, particularly in patients with a history of travel to endemic areas.
Case series of cutaneous myiasis in neglected cases of autoimmune bullous disorders. Myiasis is an infestation of the tissues and organs of living vertebrates and humans by fly larvae, usually those belonging to the Calliphoridae family. The larvae feed on the host's necrotic or living tissue. Preexisting dermatological conditions and poor hygiene have been described as predisposing factors for myiasis, and it is especially common among neglected, dependent patients. Based on our literature search, we could find only a few case reports reported on cutaneous myiasis in autoimmune bullous disorders. It is especially more common in the South Indian Tamil Nadu population due to the false belief that autoimmune blistering disorders like pemphigus and bullous pemphigoid are considered chicken pox
Case Report: Re-Emergence of Cochliomyia hominivorax in Costa Rica: Report of a Human Myiasis Case 23 Years after Elimination. The New World screwworm, Cochliomyia hominivorax Coquerel (Diptera: Calliphoridae), was officially eliminated from Costa Rica in 2000, but it was reintroduced in 2023. A myiasis by C. hominivorax in a 71-year-old man with a 4-month history of foot hyperkeratosis and interdigital ulcers is reported. The myiasis was detected before sampling for bacterial culture. Approximately 160 first- and second-instar larvae were recovered and identified as C. hominivorax. Morphological identification was based mainly on characteristics of the cephalopharyngeal skeleton, spiracles, and pigmented dorsal tracheal trunks. Sequencing of a cytochrome c oxidase subunit I gene fragment
Cutaneous myiasis by Calliphoridae dipterans in dogs from Chad. Cutaneous myiasis caused by various Calliphoridae dipteran species is prevalent worldwide and is of particular veterinary and public health concern. Recently, in a scientific exploration of the Guinea Worm Eradication Program to Chad, Africa, we observed that dogs with mutilated ears, based on local awareness, were caused by cutaneous myiasis. In this study, we analyzed epidemiological, morphological, and molecular data on cutaneous myiasis in dogs from Chad. From September to October 2022, dogs (n = 1,562) from 56 villages situated along the Chari River were physically inspected for cutaneous myiasis. All larvae were collected and identified morphologically and by molecular analysis of the partial cytochrome oxidase c
Aural myiasis in Ancient Rome: Celsus and the ear maggots. Although today there is extensive scientific literature on aural myiasis, a historical study of the subject has yet to appear. This short article reports the first description of aural myiasis in the Western medical literature. Methods involved: (1) scholarship review of ear diseases within Ancient Greek and Roman medical texts (); (2 ) linguistic analysis for text identification through the Library of Latin Texts, the and the Loeb Classical Library; and (3) translation of the Latin texts that described cases of aural myiasis with commentary. To our knowledge, the earliest case of aural myiasis in Latin medical literature is reported by the Roman encyclopaedist Celsus (first century CE). In his , he describes cases of maggot infestation
Investigation of pseudo-urogenital myiasis and errors in diagnosis. Cases of genitourinary myiasis in humans caused by larvae of flies are reported from time to time. In our study, 11 patients, who reported worms in their urine and brought these worms to our laboratory, were investigated. The larvae were found to belong to the subfamily . By taking urine samples carefully from the patients , examining and evaluating their history, it was concluded that they did not actually have myiasis. We endeavour to describe the pitfalls in this diagnosis.
Case Report: Outbreak of Nosocomial Myiasis by Cochliomyia macellaria (Diptera, Calliphoridae) in a Hospital in Colima, Mexico. Myiasis in humans is a disease caused by larvae of various fly families. It mainly occurs in communities with poor sanitation and low socioeconomic status. Meanwhile intrahospital or nosocomial myiasis represents a rare phenomenon but is of relevance to public health . Here, we report an outbreak of myiasis caused by Cochliomyia macellaria in five patients hospitalized for several diseases at the Service of Internal Medicine of the Hospital Regional Universitario de Colima, Mexico during June and July 2021. Three patients were males and two were females, aged 37 to 83 years. All were affected by myiasis caused by larvae of the fly C. macellaria. Three patients
Rat-tailed maggot urinary Myiasis. A healthy young woman presented after passing a living organism during micturition. She had recently bathed in Brazilian Pantanal wetlands. A diagnosis was made.
Severe Vaginal Myiasis: Successful Management With Ivermectin. Myiasis refers to infestation of living animals or humans by maggots or fly larvae. Urogenital myiasis is a rare condition that is linked to poor sanitary conditions and limited access to healthcare and with few published case reports. Here, we describe the case of a 67-year-old homeless woman with multiple comorbidities, who presented with extensive vaginal myiasis requiring inpatient management with ivermectin, ceftriaxone, and metronidazole and daily larvae extraction and debridement. The relevance of this case is providing a report of a successful management with ivermectin of a case of severe vaginal myiasis. Severe cases of vaginal myiasis can require repeated debridement of necrotic tissue and systemic antibiotics
A rare case of residual root myiasis caused by Clogmia albipunctata larvae (Diptera: Psychodidae). Dental injury caused by caries and trauma is the main cause of residual roots. Food trapped in the residual roots is difficult to clean. If the residual roots are not treated and cared for in time, flies can take advantage as soon as hygiene slips. Here, we present a rare case of human residual root myiasis caused by Clogmia albipunctata larvae, never previously reported. A 26-year-old lady found two active, living larvae in her mouth while brushing her teeth. She did not present with fever, pain and any uncomfortable oral feeling. The intraoral examination revealed the right second mandibular molar was severely damaged as a result of caries, leaving a residual tooth root. The mucosa above
Oral myiasis in humans. Myiasis is a parasitic infestation resulting from flies laying eggs in the host tissues. It is common in animals, but can also occur in humans, including in the oral cavity. The diagnosis is usually quite clear in endemic regions such as Brazil, but it can be challenging to clinicians in nonendemic counties when faced with a patient who has acquired the infection elsewhere . We report two clinical cases of human intraoral myiasis and discuss the diagnosis and treatment of this condition. Two men, both of whom were in situations of vulnerability presented with myiasis: the first patient had larvae infesting the alveolar ridge region after tooth extraction, while the second was diagnosed with inflammatory fibrous hyperplasia associated with larvae along the edges
The Botfly, A Tropical Menace: A Distinctive Myiasis Caused by Dermatobia hominis. Dermatobia hominis, also known as the human botfly, is native to tropical and subtropical Central and South America and seen in travelers from endemic to temperate regions including the United States and Europe. Cutaneous infestation botfly myiasis involves the development of D. hominis larvae in the skin reporting travel to Latin America and experiencing pain disproportionate to an insect bite should lead physicians to consider myiasis caused by D. hominis.
Orbital myiasis: A case report and literature review. Myiasis is a parasitic disease caused by fly larvae of the Diptera order that infest human and other vertebrate animal tissues. Orbital myiasis is a potentially destructive infestation of the orbital tissues, which may affect individuals with previous ocular diseases or disorders of consciousness. A 72-year-old man presented with a complaint to the patient's symptoms and imaging examination results, the diagnosis of orbital myiasis was made. The patient was treated by exenteration of the right orbit, and all necrotic tissues and larvae were removed. The defect was repaired via reconstruction with a pedicled musculocutaneous flap from the forehead region. Antibiotics and tetanus toxoid therapy were utilized to prevent potential bacterial infection
Pin-Site Myiasis Caused by Screwworm Fly in Nonhealed Wound, Colombia. Pin-site myiasis is an underreported complication of surgical interventions. We present a case of myiasis caused by the New World screwworm fly (Cochliomyia hominivorax) in a pin site of a chronic nonhealed wound 12 years after the intervention. This infection apparently was the result of poor perfusion of the leg.
Mastoid Cavity Myiasis: A Case Report and Review of the Literature. We report a case study of mastoid cavity aural myiasis in an urban developed setting and review the relevant literature. Retrospective case report and review of the English literature via PubMed. English-language articles concerning aural myiasis and mastoid cavity myiasis were included. Two previous case reports of mastoid cavity myiasis were identified and analyzed. Neglected mastoid cavity care, low socioeconomic status, poor personal hygiene, homelessness, and chronic suppurative otitis media are likely contributing factors to this uncommon presentation occurring in an urban setting.
Intratracheal myiasis followed by tracheal-esophageal fistula: report of a rare case and literature review. To enhance awareness of the clinical features and prevention of endotracheal myiasis. A case of intratracheal myiasis is reported. A 61-year-old male patient with a history of laryngectomy was admitted to hospital due to tracheostomal hemorrhage of 3 h duration. Intratracheal myiasis was confirmed by bronchoscopy, and the patient underwent bronchoscopic intervention, which was complicated by a tracheal-esophageal fistula and resolved by endotracheal stenting. Twenty months after stent placement, the fistula had not healed. Intratracheal myiasis has serious complications and is difficult to treat. For post-tracheostomy patients, healthcare providers and caregivers should pay attention
Ivermectin: A Novel Method of Treatment of Nasal and Nasopharyngeal Myiasis. To evaluate the efficacy of oral Ivermectin, in patients suffering from nasal and nasopharyngeal myiasis. This was a prospective study, comprising 80 patients of nasal and nasopharyngeal myiasis. Patients underwent clinical examination and nasal endoscopy at the time of presentation and findings were recorded significant at 24 and 48 h with value of ( = 0.002) and ( = 0.006) respectively. Oral Ivermectin was effective in treating nasal and nasopharyngeal myiasis, in terms of early clearance, decreased morbidity and less hospital stay. We conclude that oral Ivermectin can be used as a safe and effective method for the treatment of nasal & nasopharyngeal myiasis.
Nosocomial Myiasis Caused by Lucilia sericata (Diptera: Calliphoridae) and Neonatal Myiasis by Sarcophaga spp. (Diptera: Sarcophagidae) in Mexico The presence of nosocomial myiasis reflects a lack of adequate medical attention, due to the physical facilities and/or the health care personnel. Patients requiring special attention are more susceptible, such as those with a loss of consciousness , assisted mechanical ventilation, tracheal tubes, or nasogastric probes. Nosocomial myiasis is a rare event that has a greater occurrence in the hospitals of poor and developing countries. The two cases herein described represent the first report of nosocomial myiasis in Mexico. The causal agents were found to be and spp. The taxonomical identification of the larvae of the second and third instar
Domestically Acquired Aural Myiasis in a Tennessee Girl. We present the rare case of a 12-year-old girl from Tennessee with domestically acquired aural myiasis.
